What to do today
About Miami
Biscayne Bay, open beaches and waterfront paths make it easy to spend much of a Miami day outside. The forecast point is central Miami; a shaded street and an open stretch of Miami Beach will feel different even under the same sky.
When to check the UV here
Summer brings a higher sun and long outdoor days. A cloudy morning or an afternoon shower is not a promise of low UV for the hours in between. Read the curve for the part of the day you plan to be on the sand.
Planning your time outside
For beach days, pack a cover-up that is easy to put on between swims. Choose a shaded lunch stop before heading out, and remember the walk back from the waterfront.
How to read this forecast
The chart loads hourly model data from currentuvindex.com for 25.7617, -80.1918. Times are local to this forecast point. Open Hour-by-hour numbers for the values, or compare the next few days below the main chart.
The forecast describes UV for the area, not the dose on your skin. Buildings, trees, cloud and reflective surfaces can change your exposure. It does not measure a particular beach chair, trail or street.
What time does UV drop below 3?
Read the descending side of today’s curve, then check that the later hours remain below 3. The time changes with the date and weather. See how to find the afternoon drop instead of using a fixed clock time.
What should I bring?
Plan sun protection when the forecast reaches 3 or higher. Shade, covering, a hat, sunglasses and sunscreen work together. At very high UV, arrange outdoor time around the peak rather than relying on sunscreen alone.
